An airport is an aerodrome with extended facilities, mostly for commercial air transport. Airports usually consist of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation.

विमानक्षेत्र या हवाई अड्डा वह स्थान होता है, जहां कोई भी वायु वाहन, जैसे वायुयान (ऐरोप्लेन), हैलीकॉप्टर, इत्यादि उड़ान भरते और उतरते हैं। विमानों को यहां भंडारण भी किया जा सकता है। एक विमानक्षेत्र में कम से कम एक उड़ान पट्टी अवश्य होती है, एक हैलीपैड और टर्मिनल इमारत भी होती हैं। इनके अलावा हैंगर भी हो सकते हैं।
